Brief description |
Genes down-regulated in the normal-like subtype of breast cancer. |
Full description or abstract |
We explored whether the five previously reported molecular subtypes in breast cancer show a preference for organ-specific relapse and searched for molecular pathways involved. The intrinsic gene list describing the subtypes was used to classify 344 primary breast tumors of lymph node-negative patients. Fisher exact tests were used to determine the association between a tumor subtype and a particular site of distant relapse in these patients who only received local treatment. Modulated genes and pathways were identified in the various groups using Significance Analysis of Microarrays and Global Testing. Bone relapse patients were most abundant in the luminal subtypes but were found less than expected in the basal subtype. The reverse was true for lung and brain relapse patients with the remark that absence of lung relapse was luminal A specific. Finally, a pleura relapse, although rare, was found almost exclusively in both luminal subtypes. Many differentially expressed genes were identified, of which several were in common in a subtype and the site to which the subtype preferentially relapsed. WNT signaling was up-regulated in the basal subtype and in brain-specific relapse, and down-modulated in the luminal B subtype and in bone-specific relapse. Focal adhesion was found up-regulated in the luminal A subtype but down-regulated in lung relapse. The five major molecular subtypes in breast cancer are evidently different with regard to their ability to metastasize to distant organ(s), and share biological features and pathways with their preferred distant metastatic site. |

We need your help: Update on GSEA/MSigDB funding support
Last November we submitted a proposal to NCI's Information Technology for Cancer Research (ITCR) program for the continued
funding of GSEA and MSigDB. Unfortunately, our proposal was not funded in this round, but we were encouraged to resubmit
for the next one. This funding is critical for our continuing support and enhancement of the GSEA-MSigDB resource.
For our original submission many of you sent us emails of support, an important requirement for these grants. We
now ask for your help again. We would greatly appreciate a short email message from you describing how the resource
has been of value to your work and any concerns you may have about its continued availability.
Please send us your message of support to gsea-los@broadinstitute.org
on or before Monday June 5, 2023.
Thanks in advance for your help and support.
The GSEA/MSigDB Team.
